Similar in detail to the 135, the 235 accommodated the wider bodies typical of the early 1950s and featured the new broad grille. It offered better performance with greater compression, triple carburettors and a new camshaft, resulting in a top speed of approximately 100 mph. Gearbox choices included a synchronised four-speed unit or an optional Cotal four-speed pre-selector unit.
To launch the 235, Delahaye prepared their first example with an aluminum body by Motto that reached 173.098 km/h on the Autodrome de Linas-Montlhéry. The second car was fitted with a body by Letourneur et Marchand to the factory plans and was a huge hit at the 1951 Paris Motor Show. Delahaye offered 170 kph performance and the car achieved it with several different body styles.
